Stanwell, I'm not expert enough but too old, with only forty two years of aviation under my belt, thirty seven of it for a living. But in my younger day I'd certainly have loved to have had a go, obviously having practiced the necessary skills well in advance and made the other necessary preparations as well as this team obviously did. But I have a fair amount of close formation experience, in fact the military thought I was good enough to teach others how to do it, in both fixed wing and rotary wing. These days I fly far less exciting stuff, mainly in straight lines.
Tourist, who was informed of some basic aerodynamic facts will also be very well acquainted with flying very close to the downwash of much larger aircraft.
